LT3055IMSE-5#TRPBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT3055IMSE-5#TRPBF is a micropower, low noise, low dropout voltage (LDO) linear regulator from Analog Devices. It supplies 500mA of output current with a typical dropout voltage of 350mV at full load. The device features a ±45V input voltage rating and includes precision current limit and diagnostic functions. A 10nF bypass capacitor reduces output noise to 25μV RMS in a 10Hz to 100kHz bandwidth. It offers programmable precision current limit accurate to ±10% and a minimum output current monitor. Internal protection includes thermal limiting, reverse battery, reverse current, and reverse output protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to tape and reel packaging when sourcing. Confirm that the I-grade designation matches the required -40°C to 125°C operating temperature range for your application. Ensure compatibility with the 16-lead MSOP package dimensions and pinout. Cross-reference the datasheet revision to confirm electrical characteristics align with your design requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring high input voltage tolerance up to 45V and precise current limiting. The IMSE-5 variant provides a fixed 5V output suitable for standard logic levels. Consider the low dropout characteristic for battery-powered systems where headroom is limited. The integrated diagnostics simplify system monitoring by providing explicit fault signals for overcurrent and thermal events without additional circuitry.
